Choi Jin Xiao Bian teach you six strokes to share special black masterbatch world know the real gold
1, a higher degree of dispersion
Dedicated black masterbatch is the use of carbon black production. Since the raw carbon black covered with dust, light weight, was fluffy, unless large-scale action, otherwise it would work environment becomes dirty. Because of this, they generally choose founder dedicated black masterbatch to complete the carbon black pre-dispersion. The resin carrier is clean, free-flowing and easy to use.
Carbon black dispersion performance is difficult also plagued masterbatch manufacturers. Use single or double screw extruder production of special high-load black masterbatch dispersion is very poor. When the end-users of these black master batch mixing or special molding, its performance is only slightly better than that of carbon black, but the effect is equally unsatisfactory.
In order to achieve a stable highly dispersive, you must use a high level of shear mixer to mixed carbon black. With sufficient strength, these mixers can make carbon black and the base resin are thoroughly combined. The type of carbon black used also affects dispersion property. The smaller the particles of carbon black dispersion on the more difficult.

2, covering power stronger
Dedicated black masterbatch quality of the decision of the second factor is the covering power, coloring capacity of carbon black particles is poor, difficult to cover all the other colors in the lower, the results of the final product can only get deviated from the color. In the melting process, the correct first Optional carbon black having high coloring capability to cover the capacity of existing color is covering force.
3, better mobility
If the masterbatch itself has a good dispersion property, but it does not flow into the material to be molded, it produced the effect is not ideal. In general, for the production of masterbatch base resin has high rheology.
To save costs, some of the materials of masterbatch production of commercial reusable scrap or recycled materials as resin carrier. Thus produced masterbatch flow properties will be significantly reduced, if not good rheology, mold trade unions in cycle time trouble handling and appearance. Having a minimum dilution ratio of masterbatch can produce uniform dispersion a good black.

4, compatibility to a large
Compatibility is to determine the quality of black masterbatch special fourth factor. If you are using masterbatch chips or recycled materials produced, then it may contain contaminants or other non-meltable polymer. Then resin primer can be used to produce high quality masterbatch, masterbatch in the melting process have good compatibility. Quality masterbatches use LLDPE, LDPE, HDPE, PP, PS, SAN, PA, and other materials to produce.
5, to be consistent stability
Stability is a major manifestation smooth carbon black ratio. If the percentage of carbon black is fluctuating, the number of required molten masterbatch is not the same, to produce the same color products impossible. Of course, other factors such as injection melt flowability and dispersion property should be consistent with each batch of feeding amount.

6, shading should be clear
Finally, a special factor in determining the quality of black masterbatch is the color shades. There are various types of carbon black can be used for coloring masterbatch market, but all kinds of colors and prices are also very different. Large particles of carbon black than the small particles of carbon black has a lower degree of coloration and different background. Large particles masterbatch suitable for film production, such as garbage bags, but not for those who focus on the production of beauty products, such as TV signs or need UV protection areas such as agricultural films or external piping. For these products, you can use the higher-priced small particles of carbon black.
